Anchor Blocks for Buoys and Navigation Markers
Secure, Durable Mooring Solutions for Marine and Inland Waterways
Elite Precast manufactures heavy-duty precast concrete anchor blocks for securing buoys and navigation markers in coastal, river and inland water environments.
Designed for stability in tidal waters, flowing rivers and open marine conditions, our anchor blocks provide a straightforward and dependable anchoring solution for permanent and temporary navigation systems.
Where marker stability and long-term performance are critical, we deliver practical precast solutions.
What Are Sea Anchor Blocks?
Built for Marine Exposure
Navigation buoys and marker systems are continuously exposed to:
Tidal fluctuation
Wave action
River flow and current
Wind loading
Vessel interaction
Our anchor blocks are manufactured using high-strength, durable concrete mixes suitable for aggressive exposure classifications, including marine and tidal environments.
Delivered precast and ready to install, they allow immediate deployment without on-site curing or specialist installation processes.

Frequently Asked Questions
Are precast anchor blocks suitable for navigation buoys?
Yes. They are widely used to secure both permanent and temporary buoy installations in coastal and river environments.
How do I determine the correct anchor weight?
Weight is determined by buoy size, buoyancy, environmental loading and seabed conditions. We can assist based on your project information.
Are your blocks suitable for tidal and marine exposure?
Yes. Our concrete mixes are suitable for aggressive marine exposure classifications.
Can lifting points be included?
Yes. Cast-in lifting anchors or lifting eyes can be incorporated for safe handling and installation.
Can anchor blocks be recovered?
Yes. For temporary navigation systems, blocks can be recovered and reused subject to inspection.
Do you manufacture bespoke units?
Yes. We produce custom sizes and configurations to suit specific buoy and mooring requirements.
